When is a Dishwasher door not a dishwasher door? When it's a jar.
That's a joke by the way. It's especially a joke if you have a Siemens dishwasher who's door is not designed to be left ajar. You can have it fully open, or fully closed, but it won't rest in any position in-between unless you prop it open, e.g. with a cork or other handy item that you may have to hand, as per my picture below.
Why would I want to prop it open? Because after it's finished, if you open the door for 15 minutes then the residual heat dries the contents just nicely, as long as the steam can escape. If you don't open the door, you can look forward to plates and glasses that still need the attention of a tea towel, even several hours after the machine finishes its cycle. Leaving the door fully open is asking for a kitchen accident of course, so that's not really an option. This door ajar approach is standard practice with any dishwasher, no? Maybe I'm alone in this, but every other dishwasher I've come across neatly sits open a few inches to facilitate my whim, and it's got to be trivially easy to manufacture into the door mechanism. Certainly my posh Siemens dishwasher would look a lot better without the cork.
